Answer 1

The false statement is: "Both fast food restaurants have exactly one modal delivery time of 40 minutes."

Fast Food 1 values: 42, 38, 37, 39, 38, 40, 45, 41, 40 — modes are 38 and 40 (each appears twice), so FF1 is bimodal.
Fast Food 2 values: 40, 37, 40, 41, 38, 46, 41, 37, 40 — mode is 40 (appears three times).

All other statements (means = 40, medians = 40, no outliers by the 1.5·IQR rule) are true.
